The defender just sits in the trenches since there is no need to push on the enemy trenches. The enemy has to send soldiers down through the dead zone/no man's land where all or most will get shot down by soldiers firing from the defender's trenches or by artillery fire. In fact, many British and American soldiers died this way when arrogant generals with no trench warfare experience sent squads after squads of men to die rushing the defender trenches. The defender also has the benefit of being more prepared for the trench warfare with more time to plan trench design, better supply stocks and delivery routes. For trench design, the defender can create trenches on high ground which is a critical tactical advantage over the attacker and very difficult to break.

They improved the drainage of the trenches to reduce standing water. They also instituted regular foot inspections, greasing of toes and changes of socks. Waterproof footwear also greatly helped.

Though troops did entrench at times generally to increase the odds of survival on case of artillery attacks and frontal assaults there were never again miles of trenches as in WWI.

Sides of trenches needed to be strengthened, duck boards maintained, sand bags to be filled and re filled. Any job that had to be done to maintain a secure position

A variety of fish can be found living in marina trenches, including species like pipefish, sea bass, gobies, and cod. These trenches provide a habitat for fish that need shelter and protection, making them ideal for certain species to thrive in. Each trench may have its unique ecosystem depending on factors like water depth, temperature, and food availability.
